Patent WO-2004077755-A1 (WO)
Inventor: WINKLER CHRISTIAN
IPC: H04L12/701
Filed: 2003-03-31
Abstract: The invention relates to a method wherein data packets are respectively transmitted between an input network node and a destination network node via various transmission paths which link network nodes in a packet-switching communication network consisting of various network nodes. Multipath transmission paths are determined by initially determining at least two disjunct transmission paths between input and destination nodes. Direct transmission paths are then at least partially established in the direction of the target network nodes between the network nodes contained in the disjunct transmission paths such that at least two paths are respectively created from a network node of a disjunct transmission path in the direction of the target network nodes. Thirdly, other transmission paths leading via other network nodes are at least partially established between the remaining network nodes of the disjunct transmission paths.

Title: Brake block for railway rolling stock - has pockets to trap particles which could damage wheel tyre
Inventor: BRACK GUSTAV
IPC: F16D69/00
Filed: 1974-02-15
Abstract: The brake block has a thin steel backing plate which supports the plastic brake block. At each end of the plastic part of the block, there is an extension made of prey cast iron. Each cast iron extension has a trapezoidal pocket so that two guards are formed on either side of the hole. When the brake block is pressed onto the wheel tyre any particles such as wheel scale, sand or dust might become embedded in the plastic portion and then damage the surface of the tyre. This danger is prevented by the pocket retaining any such particles which are forced past the guard.
